Electrochemical Water Oxidation Mechanisms Involving Macrocyclic Copper(II) Complexes: Ligand Ring Size Effects on Catalytic Cycles. [PDF]

Chemphyschem
The ring size of the ligand strongly influences electronic properties, steric effects, and coordination modes of key intermediates. Both catalysts show similar energy barriers for OO bond formation, but [Cu(12‐TMC)]2+ exhibits more complex mechanisms due to ligand reorganization.

Plasma membrane calcium ATPase activity is regulated by actin oligomers through direct interaction [PDF]

, 2013
As recently described by our group, plasma membrane calcium ATPase (PMCA) activity can be regulated by the actin cytoskeleton. In this study, we characterize the interaction of purified G-actin with isolated PMCA and examine the effect of G-actin during ...
